Twelve addresses holding a combined 600 Bitcoin mined in 2010 moved funds after more than 16 years, reigniting speculation over a possible link to Satoshi Nakamoto. The coins were worth approximately $120 when mined and are now valued at roughly $48 million.
A Bitcoin wallet that had been inactive since the 2017 market peak transferred its entire holdings of 5,908 BTC, worth approximately $383 million, to a new address on July 16, 2026. The coins were originally acquired near Bitcoin's 2017 peak at around $16,000 each and have gained roughly 284% since then.
A Bitcoin wallet dormant since March 2011 transferred 15 BTC on June 2, 2026, months after receiving a legal notice via blockchain demanding proof of ownership in a $285 billion lawsuit. The wallet retained 20.55 BTC as change.
A New York judge temporarily halted a lawsuit over 39,000 dormant Satoshi-era Bitcoin wallets worth approximately $285 billion, where plaintiffs claim ownership under lost-property laws. The case involves wallets that have been inactive for over 14 years, with at least one address receiving legal notice via Bitcoin's OP_RETURN field demanding proof of ownership.
Venture fund Paradigm proposed a new design called PACTs that would allow long-term Bitcoin holders to privately timestamp proof of key control before quantum computers arrive, creating a potential rescue mechanism for vulnerable early Bitcoin holdings without moving funds onchain.
Following BIP-361's publication, Polymarket odds for "Will Satoshi Nakamoto move any Bitcoin in 2026?" climbed to 9.3%, up from 4.5% at the start of the year, drawing over $2.4 million in trading volume. Analysts noted the muted overall response suggests traders still view BIP-361 as a governance discussion rather than an imminent catalyst, but the doubling of odds signals growing market unease around Satoshi's estimated 1.1 million BTC.
Jameson Lopp and five co-authors publish BIP-361, a three-phase plan to phase out legacy signatures and freeze any unmigrated coins within five years, including an estimated 1.1 million BTC attributed to Satoshi Nakamoto.
